Patent GB-2283225-A (GB)
Title: Retainer for in-can head-generating device
Inventor: DOUGLAS KEITH WALTER
IPC: B65D79/00
Filed: 1993-10-28
Abstract: A retainer for an in-can head-generating device comprises connecting means (12) between means (10) for engaging the can wall and means (11) for holding the head-generating device, such that during heat treatment of the contents of the can the retainer distorts to a shape of which the overall dimension is increased. The retainer is injection moulded from polypropylene and features curved members (12) in which differential stress is induced on cooling due to these members (12) having both relatively thick (13) and relatively thin (14) cross-sections. The curved members (12) respond to subsequent heating, when the retainer is within a filled and sealed can, by tending to straighten and they are arranged so that this tendency compensates against overall dimensional shrinkage which might allow the retainer to shift within the can. The wall-engaging means (10) may be divided into part-circular segments, Figure 2 (not shown). <IMAGE>

Patent GB-2287843-A (GB)
Title: Off-Line Uninterruptible Power Supply
Inventor: SIVAKUMAR SESHADRI
IPC: H02J9/06
Filed: 1994-04-21
Abstract: The UPS has circuitry arranged in a battery charger configuration in mains mode and in an inverter configuration in backup mode, the two configurations sharing a number of electrical components C5/C7, C6, D1-D4, L6/L7, 30. In the mains mode, inverse diodes D1-D4 of an inverter 28 rectify the AC mains to charge the battery 18 via a power factor corrector circuit 38 and a battery charger 44. Inductors in an inverter filter 30 aid the power factor corrector 18 in ensuring that harmonic-free high power factor AC mains current is drawn for battery charging. The power factor corrector 38 is a PWM DC-DC booster and the battery charger 44 is a buck PWM DC-DC converter providing a current-limited, regulated charging voltage. In back-up mode, the battery voltage is boosted by PWM DC-DC converter 36 before application to PWM inverter 28 via a switch 48 bypassing power factor corrector 38. A mains monitor effects a transfer between mains and back-up mode if either the mains voltage or frequency is too low or too high. Monitoring of the mains supply and control of the inverter 28 involve use of Kalman filter based DSP models. <IMAGE>

Title: Fusible plug for pressure vessels
Inventor: HAMMOND CHARLES PETER
IPC: F16K17/38
Filed: 1995-02-27
Abstract: A fusible plug assembly adapted to be fitted to the wall of a pressure vessel has a body 1 having a stepped cylindrical through bore 8, 9 which is plugged at its outer end 8 by a billet 2 of eutectic material. An integral piston/seal 3 is housed in bore portion 9 and being subject to pressure within the vessel is urged against the billet 2. On reaching the melting point of the eutectic material, the molten billet 2 is expelled from the bore by the ram action of the piston/seal 3 which is itself subsequently expelled under pressure. This results in the bore 8, 9 being cleared to provide an exhaust port through which pressure in the vessel can be released. The annular lip on piston/seal 3 provides pressure-assisted sealing. Composite piston/seals are described. The plug may be used in an aircraft wheel, which is described (Fig. 3, not shown). <IMAGE>

Patent GB-2305006-A (GB)
Title: Manufacture of switchgear
Inventor: CORCORAN JOHN
IPC: H02B13/00
Filed: 1995-09-01
Abstract: An electrical switchboard is produced by assembling a frame using vertical and horizontal frame members 30, 31 connected to a base plate (32, Fig 3). Compartment side plates 34 and base plates 37 are mounted on the frame members to define compartments within which mounting plates of pre-assembled modules are mounted. Electrical components 43 on the modules are connected to main bus bars 20 by feeder bus bars 22 which extend through apertures 36 in the side plates 34. These apertures are covered by arc extinction barrier plates 45 of a plastics material which is highly insulative and has a high mechanical strength. The feeder bus bars 22 extend in a tight fit through apertures within the barrier plates. At intervals along the main bus bars, arc extinction barriers (51, Fig 7) are mounted each comprising two interconnecting halves (52) forming a tight fit around the bus bars 20. The barriers (51) are mounted on plates (57) connected to the frame members 30, 31. After mounting doors and enclosure panels around the main bus bars, the switchboard is tested at a voltage of 2 to 3 kV for more than 40 seconds.

Patent GB-2296778-A (GB)
Title: A method for testing the reliability of a dielectric film on semiconductor substrate
Inventor: OM KUM-YONG
IPC: G01R31/12
Filed: 1995-12-29
Abstract: The method comprises the steps of: establishing a current value corresponding to a first set time increment in which current is first applied for testing the reliability of the film; applying the established current to the film; applying a current in each succeeding time increment 0, 2, .... 16 and measuring the charge applied until the film breaks down. The current in each succeeding time increment is increased. The current value in each time increment is itself divided by a predetermined denominator value and the divided value applied incrementally to the film (Fig. 3 not shown). The determination of breakdown is made at a predetermined delay after the application of the divided value increment (Fig.3). The method enables reliability dependent on breakdown of the film as well as degradation in performance due to hot carrier injection to be investigated. Coarse measurement can be made by dividing the increments by a low number eg 3. More discrimination can be obtained by dividing by larger numbers eg 25. <IMAGE>

IPC: G01Q60/18
Filed: 1996-04-30
Abstract: For determining the optical aperture diameter 'd' of a tip suitable for use in near-field scanning optical microscopy (NSOM), light from a source L is directed through the tip and the far-field angular intensity distribution I(* capital Greek theta*) of light emitted from end is determined using a detector D, the angle '* capital Greek theta*' being that formed between the direction of travel of the light and the perpendicular to the plane of the aperture. A single detector may be moved to several discrete measurement positions or scanned using a motor, or an array of fixed detectors may be used. Crossed polarisers P and A may be used. The intensity distribution function I(* capital Greek theta*) depends sensitively on the diameter 'd', and several functional relationships between I(* capital Greek theta*) and 'd' for light of wavelength * small Greek lambda * may be used to measure tip diameters in the range * small Greek lambda */6 < d < * small Greek lambda *.

Patent GB-2335588-A (GB)
Title: Percolator
Inventor: O'NEILL ROBERT ANDREW
IPC: A47J31/053
Filed: 1998-03-16
Abstract: An electrically powered percolator makes use of a thick film electric heating element 10 having a printed circuit track arranged to define two or more discrete heating zones 2-1, 2-2 each of which has an associated percolator structure 21-1, 22-2 delivering hot water to the filter basket 23 of the percolator. By this means, and taking advantage of the high power output of thick film heating elements, percolation time can be significantly reduced. Control of percolation is also facilitated since a bimetallic sensor on the underside of the heating element will sense the temperature of the water in the percolator with only a small thermal lag. The bimetallic sensor can advantageously be employed additionally to switch on a keep warm element portion of the thick film element when it switches off the element portions responsible for effecting percolation.
